A New Theory Of Mass Extinction. Supervolcanos. It's pretty neat how scientists discovered their presence. I saw a show, I think it was NOVA, about supervolcanos last night. Actually one of them is in Yellowstone National Park and could blow in the next couple thousand years. Aren't we the lucky ones? As a species we developed at quite an opportune time. And at least you and I don't have to worry about being annihilated. Maybe it's the earth's way of changing the dominant species. Unless we figure out a way to preserve our habitat and create a society that with the technology to battle the most destructive force on this planet, North America is doomed sooner or later. Let's face it, we are dinosaurs, as the saying goes.  ¶ 6:08 AM
